LIFE-PRESERVER.

SPECIFICATION forming part of Letters Patent No. 637,872, dated November28, 1899.

Application iiled July 21, 1899. Serial No. 724,719. (No model.)

LifeBelts; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the saine.

This invention relates to a life-belt, with a number of flat metalshells connected together by straps or belts, which shells are filledwith elastic shells wherein smaller closed receptacles made of elasticmaterial are placed. By means of this arrangement a much greatersecurity is obtained than is possible with the known life-belts withsingle metal shellssuch, for example, as those described in the UnitedStates Patent Specification No. 436, 31S

and the British Patents Nos. 5,7l0and 14,061'

of 1S87-since the carrying or supporting power of the elastic shells andreceptacles contained therein is not interfered with by damage to one ofthe metal shells.

In the accompanying drawings a life-belt of this kind is shown extendedin Figures l and 2, in outside and inside elevation, respectively. Fig.3 shows a transverse section through the extended life-belt. Fig. 4shows the life-belt' fastened to the body. Fig. 5 shows one of the metalshells in elevation. Fig. 6 is a vertical section; Fig. 7, a verticaltransverse section taken on line a; m of Fig. 6, and Fig. 8 a horizontalsection taken on line a' z of said Fig. 6.

The life-belt consists, essentially, of' a number of flat metal shellsA, which are connected together by Vstraps or belts. In the arrangementshown in Figs. l and 2 the metal shells A are placed in separatepockets. They can, however, be also secured directly to the connectingstraps or belts.

The fiat metal shells A, fitting the curvature of the body, are providedwith an opening D for inserting long shells B, which are madeof elasticmaterial and are filled with smaller cylindrical, spherical, orotherwise suitably formed receptacles C, which are like- Wise elastic.By reason of this arrangement section, and of less diameter than lengthand width, said cases united at one end by a Waist-belt, and near theother by an encom-A passing strap, in combination with flexible cellularcases filling said metallic cases, for4 the purpose set forth.

2. A life-preserver comprising a series of metallic cases concavo-convexin horizontal section and of less diameter than length and width, thosecases on a line with the armpits shorter than the others, said casesunited at oneend by a waist-loelt and near the opposite end by anencompassing strap, in combination with cellular flexible cases fillingsaid metallic cases and having cells of dierent internal areas, for thepurpose set forth.

3. A life-preserver comprising a series of metallic cases concavo-convexin horizontal section and of less diameter than length and width, asuitable pocket for each ofsaid cases, a Waist-belt uniting said casesat one end, and an encompassing strap uniting the same near theiropposite end, those cases in line with the armpits shorter than theothers, in combination with flexible cases filling said metallic casesand filled with flexible cases forming air-chambers, for the purpose setforth.

4E. A life-preserver comprising a series of metallic casesconcavo-convex in horizontal section and of less diameter than lengthand width, a suitable pocket for each of said cases,

a waist-belt uniting said cases at one end and an encompassing strapuniting the same at their opposite end, those cases in line with thearmpits shorter than the others, in combination with flexible casesfilling said metallic cases, and filled with fiexible cases formingair-chambers of diierent capacities, for the purpose set forth.
